| Abstract: |
Chaetoceros muelleri is a favorable food for the larvae of shellfishes and other marine animals.
At a temperature of 25-30.5℃, light intensity 1, 000-1, 100 lux, and pH 7.98-8.48, experiments were carried out to find the optimum salinity, phosphate, and nitrate concentration for the growth of this small diatom.
The following are the results of the present investigation:
(1) The optimum salinity is 25.9‰ (17-32.21‰).
(2) The suitable phosphate concentration is PO4-P 19.9-139.3 μg-at/1, and the optimum concentration is 99.5 μg-at/1.
(3) The suitable nitrate concentration is NO3-N 1, 976-7, 904 μg-at/1, and the optimum concentration is 5, 928 μg-at/1. |
